Lindgren played approximately half of Opeth's lead guitar sections. As explained in "The Making of Deliverance and Damnation" on Opeth's live DVD Lamentations, lead-playing duties were based on ease of Mikael Åkerfeldt's vocal delivery and which of the two might want a given solo more. If Åkerfeldt was having trouble with a solo, he would hand it over to Lindgren, and vice versa. In March 2004, Peter (and Mikael Åkerfeldt) were both ranked #42 out of the 100 Greatest Heavy Metal Guitarists of all time by Guitar World.
In May 2007, Peter Lindgren announced that he had left Opeth due to the rigors of life on the road as a touring musician and that he had lost his enthusiasm for playing in Opeth. Both Lindgren and Åkerfeldt said that the split was amicable. Lindgren was replaced by Fredrik Åkesson, a member of Arch Enemy. As of this time Lindgren was working as an information technology consultant in Stockholm and has so far stayed out of public eye.
